In Great Britain May 11, 1949 2 Claims. (Cl. 242158) This invention hasreference to building mechanism for package of textile yarns in textilemachines wherein yarn is built into packages on bobbins, tubes or thelike mounted on vertical spindles, by the up and down reciprocation ortraverse of a device such as a ring rail, the general construction ofsuch machines being well known and understood in the textile industrythough the machines are not all alike in detail and are known under manynames.

The present invention has for its object to provide improved mechanismfor controlling the traverse of the ring rail or of the spindle railwhich shall be more efficient than mechanism used at present for thispurpose and which is especially useful for the building of largepackages of rayon, though not limited to such use, whereby betterpackages are built and variations in the type and shape of the packagesare easily and exactly effected, the mechanism being strong and ofcomparatively simple construction.

According to this invention yarn package building mechanism for textilemachinery of the kind referred to comprises two stop members mounted onreciprocating members actuated by a suitable rotary part of the machineone at least of these stop members being automatically and progressivelymoved along the reciprocating members from zero to maximum and backduring the running of the machine, whereby the two stop members engageand move arms on a direction controlling mechanism to reverse thedirection of movement of the ring rail, or of the spindle rail at apredetermined position according to the setting of the mechanism.

The invention is more particularly set forth with reference to theaccompanying drawings in which:

Fig. 1 is a front elevation of the mechanism.

Fig. 2 is an end elevation partly in section looking in the direction ofthe arrow in Fig. 1.

Fig. 3 is a plan of the compound lever.

Fig. 4 is a front elevation of the compound swinging arms.

Fig. 5 is a plan of Fig. 1.

Figs. 6, 7 and 8 are detail detached views of parts of the largerfigures, immediately adjacent.

The building mechanism shown in the drawings is mounted at one end ofthe machine, the end plate 6 of which is shown in section in Figs. 2 and8 butis not shown in Fig. 1: by mounting the mechanism on the end plateof the machine it is in a convenient position for its working and iseasily accessible.

The mechanism has two parallel rods J above and 8 below both slidablymounted in two brackets 9 and I0 (9 not being shown in Fig. 2) which aresecured to the end plate 6 by nuts and bolts] I. The rods 1 and 8 aremounted to slide parallel with the end frame plate 6 and are secured atthe ends by bridge pieces 12 secured by bolts l3.

The bottom rod 8 has a toothedrack .14 on its under face engaged by apinion IS on a short shaft l6 at the other end of which is a sprocketwheel I! driven by a chain It from a sprocket, not shown in thedrawings, on the liftershaft on the machine, which shaft, constantly.changing its direction of rotation, in a mannerdescribed later herein,reciprocates the two rods 1 and 8.

Mounted on the rods 1 and 8 is a member 19 having an upwardly extendingarm 20 secured to it at the top and having between therods, a transverseextension 2| bored to form a bearing for a short shaft 22 having on itsback end a ratchet Wheel 23 in front of which is acam plate 24 with acam groove in its front face, While at the front end of the short shaft22 is a toothed shock wheel 25, having above it a spring pressed pawl 26which holds the wheel steady but can be over ridden when. the wheel isturned.

The upward extending arm 2!! which rises above the top edge of the camplate 24 has mounted in it at the top two compound swinging arms 21shown separately in Figs. 3 and 4.

These arms are not of the same length, nor are they aligned, the longerarm 28 has a ,slot 29 and the shorter arm 3ll angularly disposed to thearm 28 as shown in Fig. 4 has an opening 3| in which a short stud ismounted carrying a roller 32 running in the cam groove '33 of the camplate 24, the cam groove 33 being a heart shaped cam giving a straightline motion.

Mounted in the slot 29 of the other arm is a slider having on it aroller 34, the slider being adjustable at any position in the slotandheld by the nut 35, and the roller is in a vertical slot 36 in abridge member 31. On the bottom end of the slidable bridge member 31 is.an adjustably mounted stop 38 and opposite but not in line is a similarstop 39 on a bridge member 40 slidable on the rods 1 and B when it isdesired to move it, but normally held in a fixed position by a grubscrew 41.

On the brackets 9 and Hi and at the back near the plate 6 is a bar 42having slots 43 near its ends so that it can be adjusted to and 'froasrequired and can be held by screwing down the screws 44 whose shankspass through the slots 3 43. This bar 43 has on it a spring pressed pawl45 which is in line with the ratchet wheel 23: the pawl 45 can beadjusted up and down by altering the nut 46 on its top end.

The two adjustable stops 38. and 39 project downwardly as shown andwhile they "area on the same level they are not opposite but are side byside. engage a separate lever 50 below when it--the' pawlis moving inone direction buti'n'ot to? operate it when moving in the otherdirection.

These levers serve, when operated, to reverse the direction of rotationof..the lifter.'shaft; and" the particular mechanism by which this isdone is not part of the invention so long as the stop 38 when moving inone direction moves *over a' lever which reverses the directionofrotation;

Each of these stops is designed to.

the teeth, the check pawl 26 holding the wheel 25 and through it theratchet wheel 23. It will be appreciated that by moving the spring pawl45 toward or from the ratchet wheel 25 the number of teeth the ratchetwheel can be notched-on 'b'ya-the pawlcanabe: varied; within theadjustable limits.

When the machine is working, and considering Figs. 1 and 5, the rods 1and 8 and all they and the stop 39 when moving in theopposite directionengages its lever and reverses the direction. of rotation the two stopsthus constantly reversingQ'the direction of. rotation; that" is all thatis required of L them. It is convenientfor the levers engagedf toactuate. electrical apparatusorother' means to give the necessary rapidreversal.

' When the machineis to'be used, the size'and shape of l the packages tobe wound" are. known andthemechan'ism'is set accordingly; theposi tionof the stop 39' fixing the bottom of the package-tl-ie stop which ismovable; fixing'the top of the package.

7 The invention-can'be used with a machine having either a rising; and"falling'ringmailthe spindle level being fixed; or with" rising'and'iallling. spindles, the level: of thering rail being fikedIFor thepurpose of this description, it willlhdwever bev assumed thatthe ring?rail rises andi'falls and thaspindles'do not. On this as sumptionthebridg'e 40 and; the stop 39icarried by. it"ar'e adjusted to thebottom of the package at which. level the stop 38' reversesfthe'direction oflrotation of the liftershaft sothat the ring raill'risestillthe stop 38' engages" its lever and again reversesthedirectionofrotation.

Wfiena flat based package is to be'b'uilt the reversal of" direction ofrotation at the'bcttom will always be at the same level so thestop 39can be adjusted to the bottom" position and fixedl Thev top of thepackage will; however becontinually rising on the spindle-until themaximum top position is reached, and consequently'the other stop? 38must'be movable so thatit efiects a reversal of the.d'ir'ectioncfrotation. at" difierent levels.-

'I helrequired variation of thelevel of: reversal effected by the stop38"i's' efiected by first slackening the nut 3563 which the'r'oller 34is'heldin its adjusted positionin the slo't 2'9 'of'the long arm of 'thecompound'lever 21'. bridge member 31' to be slidto' and fro" on the rodsland 8" to the desired position, and'the releasing-ofithe roller whichcan th'uslmove'up and down the slot 29 and alsothevertical slot 36 inthe bridge member 2 1. When the. desired ad'- ju'st'ment' of theposition of the bridge member 37 has been made the nut 35 is secured" tofix the position of-the roller in the slot 29 and" also, though. it canslide up' and down therein in the slot 36'.

The position of the spring.pawl45 isadjusted as this pawl, which is" in"linewith' the ratchet wheel 23 will. engageteeth of the'wheel as it ismoved to and'fro by the reciprocation of the ro'dsl and 8': inonedirection the pawl turns the wheel and-in the other itdoesnot, butoverrides This; allows the 7 'carryare atone 'endfof their travel, andthey have moved to the left hand side. One of the stops 38 01339comesinto operation at this point and the direction -offthefwheel" I! isreversed from the reversalof'directiorr-or rotation of the lifter shaftand the rods land 8 move to the right and in dueicourse the ratchetwheel 23 is engaged by the spring pawl 45 and is notched-on one or moreteeth. and; turned. This turning also turns the cam plate 24 which movesthe short arm 30 of the compound .swingingarms 21, whose rolleriis in?the cam'groove', and" it also moves the long arm'28 carryinggtheroller34 slidab'lein'the verti caILsIot 36 in" the b'ridge member 3T,andiconsequently th'e'bri'dgefmember' 3Tandits stop" 38"are movedto' andfrom the-stop 3'9.

The distance: between the stops 38 and" 39" is thus 'widened' upito. amaximum'and then nar rowed to a. minimum and this .movement' continuesas longas .the machine is running.
